Subject: [PATCH] Bug 14708: The patron set as the anonymous patron should not
 be deletable.

Right now it's possible to delete the anonymous patron at any time. When this happens the system will break just as if anonymouspatron was unset but patrons still have an "always anonymize" privacy setting.

This issue occurs more frequently than one would expect.

We should make it so that the patron set in AnonymousPatron is not deletable.

Test Plan:
1) Apply this patch
2) Set a patron to by AnonymousPatron
3) Attempt to delete that patron from the members toolbar
4) Note the error message!
